First thing I noticed is that she's only up 1.5-2 hours. Actually at 7 months your lo is probably pushing 3 hours of "A" time, maybe a little more. That should extend naps somewhat during the day, 2 naps of about 1.5 hours each, if you feel that she needs it.
As for early wake-ups, It's ok to just let her talk
You don't have to go to her until she really needs you. Sometimes they just fall back to sleep on their own. If you let her go, she may adjust her schedule on her own and start sleeping a little longer. Mine often does the same thing, and she'll happily play in her crib until we go get her.
